we developed an automated camera trap for phototactic insects a few years ago and are planning on further developing our system to also assess diurnal pollinating insects, as part of a federal research project.
Does anyone have any useful tips regarding the colours that are best for attracting pollinating insects? I saw that @Max_Sitt you used blue, white and yellow "flowers" to attract insects in your system. Would you be willing to share any information on how well these colours worked for attracting different insects? I would be very grateful for your help :D
